Real Time Data Grid Part 2/2 - Conclusion
(Page 6 of 6 )

By combining ASP, JavaScript, and some COM functionality through the XMLHTTP class, we can create highly functional pages that can work with a remote web server without the visitor even knowing what's going on!

The DynamicGrid class described in this article has limited functionality, and could be improved on to add a host of other features, including the ability to select the table to view using a HTML form, paging the records in a recodset instead of only displaying a fixed about on a page, sending the data to the server as XML, etc.

There are several ways that you could use the DynamicGrid class as well. If you're hosting on a Windows 2000 server and don't have access to Enterprise Manager, then you could use the DynamicGrid class to update your databases. With a bit of work, it could also be used to backup databases or copy them to a different server.
